"Hobbes's Materialism in the Early 1640s" (pdf) (British Journal for the History of Philosophy 13:3 (2005), 437 – 448)
I argue that Hobbes isn't really a materialist in the early 1640s (in, e.g., the Third Objections to Descartes's Meditations). That is, he doesn't assert that bodies are the only substances. However, he does think that bodies are the only substances we can think about using imagistic ideas.
"Knowledge of God in Leviathan" (pdf) (History of Philosophy Quarterly 22:1 (2005), 31-48)
Hobbes denies in Leviathan that we have an idea of God. He does think, though, that God exists, and does not even deny that we can think about God, even though he says we have no idea of God. There is, Hobbes thinks, another cognitive mechanism by means of which we can think about God. That mechanism allows us only to think a few things about God though. This constrains what Hobbes can say about our knowledge of God, and grounds his belief in a fairly strong version of the thesis that God is incomprehensible.
